植物提取修复矿区重金属污染土壤研究现状

矿区土壤重金属污染日益严重,使用传统的物理和化学修复方法成本高,对环境扰动大,而利用植物修复的效果较为明显,易于操作。对植物修复技术进行了简要的介绍,从超富集植物、受污染土壤中重金属的状态及添加螯合剂提高植物修复效率等方面重点阐述了植物提取作用,最后简述了植物提取在矿区的应用及目前存在的问题。

Research Status of Heavy Metal Extracting from Contaminated Soil in Mining Areas by the Plants

Heavy metal pollution in mining area is becoming worse and worse now and it is high costly to use traditional methods of physical and chemical Method of physical and chemical remediation it also causes environmental disturbances at the same time,but the remediation is more and more obvious by using phytoremediation ,which is easy to operate. This article provides a brief introduction on the phytoremediation effect, emphatically elaborates plant extraction role from the perspective of super-enrichment plant, the status of heavy metals in contaminated soils, adding a chelating agent to improve efficiency,and finally briefly introduc its application in mining area and existing problems.
